Added an option to configure locality load balancing settings for each targeted service via destination rule #18406. Fixed an issue where pods crashing would trigger excessive Envoy proxy configuration pushes #18574. Fixed issues with applications such as headless services to call themselves directly without going through Envoy proxy #19308. Added detection of
